<a name="gst-plugins-base-plugins-xvimagesink.implemented-interfaces"></a><h2>Implemented Interfaces</h2>
<p>
GstXvImageSink implements
 <a href="../html/GstNavigation.html#GstNavigation-struct">GstNavigation</a>,  <a href="../html/GstVideoOverlay.html#GstVideoOverlay-struct">GstVideoOverlay</a> and  <a href="../html/GstColorBalance.html#GstColorBalance-struct">GstColorBalance</a>.</p>
</div>
<div class="refsect1">
<a name="gst-plugins-base-plugins-xvimagesink.description"></a><h2>Description</h2>
<p>XvImageSink renders video frames to a drawable (XWindow) on a local display
using the XVideo extension. Rendering to a remote display is theoretically
possible but i doubt that the XVideo extension is actually available when
connecting to a remote display. This element can receive a Window ID from the
application through the <a href="../html/GstVideoOverlay.html#GstVideoOverlay-struct"><span class="type">GstVideoOverlay</span></a> interface and will then render
video frames in this drawable. If no Window ID was provided by the
application, the element will create its own internal window and render
into it.</p>
<div class="refsect3">
<a name="id-1.2.117.8.3"></a><h4>Scaling</h4>
<p>The XVideo extension, when it's available, handles hardware accelerated
scaling of video frames. This means that the element will just accept
incoming video frames no matter their geometry and will then put them to the
drawable scaling them on the fly. Using the <a class="link" href="gst-plugins-base-plugins-xvimagesink.html#GstXvImageSink--force-aspect-ratio" title="The “force-aspect-ratio” property"><span class="type">“force-aspect-ratio”</span></a>
property it is possible to enforce scaling with a constant aspect ratio,
which means drawing black borders around the video frame.</p>
</div>
<div class="refsect3">
<a name="id-1.2.117.8.4"></a><h4>Events</h4>
<p>XvImageSink creates a thread to handle events coming from the drawable. There
are several kind of events that can be grouped in 2 big categories: input
events and window state related events. Input events will be translated to
navigation events and pushed upstream for other elements to react on them.
This includes events such as pointer moves, key press/release, clicks etc...
Other events are used to handle the drawable appearance even when the data
is not flowing (GST_STATE_PAUSED). That means that even when the element is
paused, it will receive expose events from the drawable and draw the latest
frame with correct borders/aspect-ratio.</p>
</div>
<div class="refsect3">
<a name="id-1.2.117.8.5"></a><h4>Pixel aspect ratio</h4>
<p>When changing state to GST_STATE_READY, XvImageSink will open a connection to
the display specified in the <a class="link" href="gst-plugins-base-plugins-xvimagesink.html#GstXvImageSink--display" title="The “display” property"><span class="type">“display”</span></a> property or the
default display if nothing specified. Once this connection is open it will
inspect the display configuration including the physical display geometry and
then calculate the pixel aspect ratio. When receiving video frames with a
different pixel aspect ratio, XvImageSink will use hardware scaling to
display the video frames correctly on display's pixel aspect ratio.
Sometimes the calculated pixel aspect ratio can be wrong, it is
then possible to enforce a specific pixel aspect ratio using the
<a class="link" href="gst-plugins-base-plugins-xvimagesink.html#GstXvImageSink--pixel-aspect-ratio" title="The “pixel-aspect-ratio” property"><span class="type">“pixel-aspect-ratio”</span></a> property.</p>

 A pipeline to test hardware scaling.
When the test video signal appears you can resize the window and see that
video frames are scaled through hardware (no extra CPU cost). By default
the image will never be distorted when scaled, instead black borders will
be added if needed.</p>

now and it will be distorted to fill the entire frame instead of respecting
the aspect ratio.</p>

 A pipeline to test navigation events.
While moving the mouse pointer over the test signal you will see a black box
following the mouse pointer. If you press the mouse button somewhere on the
video and release it somewhere else a green box will appear where you pressed
the button and a red one where you released it. (The navigationtest element
is part of gst-plugins-good.) You can observe here that even if the images
are scaled through hardware the pointer coordinates are converted back to the
original video frame geometry so that the box can be drawn to the correct
position. This also handles borders correctly, limiting coordinates to the
image area</p>

<p>
 This is faking a 4/3 pixel aspect ratio caps on video frames produced by
videotestsrc, in most cases the pixel aspect ratio of the display will be
1/1. This means that XvImageSink will have to do the scaling to convert
incoming frames to a size that will match the display pixel aspect ratio
(from 320x240 to 320x180 in this case).</p>
